Parsing comma-separated data

There are multiple table data formats. CSV (comma-separated values) is one of the most basic formats largely used for data transport and export. There is no standard that defines CSV, but the format itself is described in RFC 4180.

This recipe introduces how to parse CSV-formatted data comfortably.

How to do it...

1. Open the console and create the folder chapter02/recipe10.
2. Navigate to the directory.
3. Create a file named data.csv with the following content:

        "Name","Surname","Age"
        # this is comment in data
        "John","Mnemonic",20
        Maria,Tone,21

4. Create the data.go file with the following content:

        package main

        import (
          "encoding/csv"
          "fmt"
          "os"
        )

        func main() {

          file, err := os.Open("data.csv")
          if err != nil {
            panic(err)
          }
          defer file.Close()

          reader := csv.NewReader(file)
          reader.FieldsPerRecord = 3
          reader...
